High antibiotic resistance is seen in bacterial infections caused by members of the genus Aeromonas [1]. They are amid the most common diseases of fish especially those in pond systems containing recirculation [2]. The emergence of resistance to antimicrobial agents in bacterial pathogens is a global public health problem [3]. A. hydrophila is a microorganism widely distributed in nature: in wa...

Aeromonas hydrophila is a Gram-negative bacterium that is pathogenic in fish, causing motile aeromonad septicaemia. It can enter (invade) fish cells, and survive as an intracellular parasite. The host-pathogen interaction and signal transduction pathway were studied by screening signal transduction inhibitors using carp epithelial cells and a virulent strain of the bacterium, PPD134/91. Geniste...

Surveillance of bacterial susceptibility to five antimicrobial agents was performed during a 1-year period in and around four freshwater fish farms situated along a stream in western Denmark. Besides assessing the levels of antibiotic resistance among the culturable fraction of microorganisms in fish, water, and sediment samples, two major fish pathogens (88 Flavobacterium psychrophilum isolate...

Characteristics of bacterial clearance were investigated in the purple sea urchin, Strongylocentrotus purpuratus (Echinodermata: Echinoidea). Primary clearance kinetics were determined for three bacteria, a marine Gram negative motile rod, a marine Gram positive non-motile rod, and a Gram negative freshwater fish pathogen, Aeromonas salmonicida. Clearance kinetics differed for each of the three...

Aeromonas hydrophila virülens özellikleri açısından önemli bir patojen olup balıklarda ölümcül hastalık olan Motile Septisemisine (MAS) neden olur. Bu çalışmada hasta balıklardan izole edilen 20 A. suşunun ve ATCC 7966 28 farklı antibiyotiğe karşı duyarlılığı araştırılmıştır. Araştırmada suşlarında antibiyotik duyarlılık profilleri Kirby-Bauer disk difüzyon yöntemiyle saptanmış heri suşa ait Ço...

An easier assessment model would be helpful for high-throughput screening of Aeromonas virulence. The previous study indicated the potential of Tetrahymena as a permissive model to examine virulence of Aeromonas hydrophila. Here our aim was to assess virulence of Aeromonas spp. using two model hosts, a zebrafish assay and Tetrahymena-Aeromonas co-culture, and to examine whether data from the Te...

Aeromonas spp is recognized as pathogenic to humans after consumption of contaminated water and food. In the present investigation, 2,323 rectal swab samples from newborns hospitalized in Rio de Janeiro were evaluated with a view to isolating Aeromonas. The samples were collected and sent to the national reference laboratory for cholera and other bacterial intestinal infections, at the Oswaldo ...

Acinetobacter baumanii is a Gram-negative, non-fermenting, oxidase-negative and non-motile coccobacillus, [1]. It can survive in water, soil, surface of skin and hospital environment. It cause a series of opportunistic infections such as epidemic pneumonia, skin and soft tissue infections, bacteraemia, urinary tract infections and septicemia app:addword:septicemia in immunocompromised patients,...
